-
protein
any of a large group of nitrogenous organic compounds that are essential constituents of living cells; consist of polymers of amino acids; essential in the diet of animals for growth and for repair of tissues; can be obtained from meat and eggs and milk and legumes
-
carbohydrate, saccharide, sugar
an essential structural component of living cells and source of energy for animals; includes simple sugars with small molecules as well as macromolecular substances; are classified according to the number of monosaccharide groups they contain
-
lipid, lipide, lipoid
an oily organic compound insoluble in water but soluble in organic solvents; essential structural component of living cells (along with proteins and carbohydrates)
-
nucleic acid
(biochemistry) any of various macromolecules composed of nucleotide chains that are vital constituents of all living cells
-
capsid
the outer covering of protein surrounding the nucleic acid of a virus
-
gluten
a protein substance that remains when starch is removed from cereal grains; gives cohesiveness to dough
-
ribose
a pentose sugar important as a component of ribonucleic acid
-
recombinant protein
a protein derived from recombinant DNA
-
actomyosin
a protein complex in muscle fibers; composed of myosin and actin; shortens when stimulated and causes muscle contractions
-
aleurone
granular protein in outermost layer of endosperm of many seeds or cereal grains
-
amyloid
(pathology) a waxy translucent complex protein resembling starch that results from degeneration of tissue
-
apoenzyme
a protein that combines with a coenzyme to form an active enzyme
-
compound protein, conjugated protein
a protein complex combining amino acids with other substances
-
enzyme
any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions
-
fibrin
a white insoluble fibrous protein formed by the action of thrombin on fibrinogen when blood clots; it forms a network that traps red cells and platelets
-
filaggrin
the main protein of the keratohyalin granules
-
growth factor
a protein that is involved in cell differentiation and growth
-
haptoglobin
a protein in plasma that binds free hemoglobin and removes it (as from wounds)
-
iodinated protein, iodoprotein
a protein that contains iodine
-
nucleoprotein
any of several substances found in the nuclei of all living cells; consists of a protein bound to a nucleic acid
-
opsin
retinal protein formed by the action of light on rhodopsin
-
phosphoprotein
containing chemically bound phosphoric acid
-
plasma protein
any of the proteins in blood plasma
-
PSA, prostate specific antigen
a protein manufactured exclusively by the prostate gland; PSA is produced for the ejaculate where it liquifies the semen and allows sperm cells to swim freely; elevated levels of PSA in blood serum are associated with benign prostatic hyperplasia and prostate cancer
-
proteome
the full complement of proteins produced by a particular genome
-
simple protein
a protein that yields only amino acids when hydrolyzed
-
beet sugar
sugar made from sugar beets
-
cane sugar
sucrose obtained from sugar cane
-
cytokine
any of various protein molecules secreted by cells of the immune system that serve to regulate the immune system
-
deoxyribose
a sugar that is a constituent of nucleic acids
-
fat
a soft greasy substance occurring in organic tissue and consisting of a mixture of lipids (mostly triglycerides)
-
ferritin
a protein containing 20% iron that is found in the intestines and liver and spleen; it is one of the chief forms in which iron is stored in the body
-
triglyceride
glyceride occurring naturally in animal and vegetable tissues; it consists of three individual fatty acids bound together in a single large molecule; an important energy source forming much of the fat stored by the body
-
invert sugar
a mixture of equal parts of glucose and fructose resulting from the hydrolysis of sucrose; found naturally in fruits; sweeter than glucose
-
maple sugar
sugar made from the sap of the sugar maple tree
-
monosaccharide, monosaccharose, simple sugar
a sugar (like sucrose or fructose) that does not hydrolyse to give other sugars; the simplest group of carbohydrates
-
oil
a slippery or viscous liquid or liquefiable substance not miscible with water
-
oligosaccharide
any of the carbohydrates that yield only a few monosaccharide molecules on complete hydrolysis
-
phospholipid
any of various compounds composed of fatty acids and phosphoric acid and a nitrogenous base; an important constituent of membranes
-
polyose, polysaccharide
any of a class of carbohydrates whose molecules contain chains of monosaccharide molecules
-
antibody
any of a large variety of proteins normally present in the body or produced in response to an antigen which it neutralizes, thus producing an immune response
-
jaggary, jaggery, jagghery
unrefined brown sugar made from palm sap
-
wax
any of various substances of either mineral origin or plant or animal origin; they are solid at normal temperatures and insoluble in water
