Title
Free-aldehyde form of glucose
Caption
Ball-and-stick models of the free-aldehyde form of glucose shown extended (top) and folded (bottom). Note that in the folded model the oxygen atom on the fifth carbon is near the carbonyl carbon.

Title
Fatty acid composition of common oils and fats
Caption
The bar graph shows the variations in percentages of saturated and unsaturated fatty acids for some common oils and fats.
Keywords
oil, fat, saturated, unsaturated, monosaturated, polyunsaturated, fatty, acid

Labeled

Title
Protein molecule segment
Caption
(a) Structural formula of a segment of a protein molecule. (b) A space-filling model of a segment of a protein chain.
Keywords
protein, segment, model, life, copolymer, amino, acid

Labeled

Title
Enzyme action
Caption
The lock-and-key model for enzyme action is represented here. Another model, called induced fit, accounts for cases where shapes of the substrate and active site are not perfectly complimentary, and the active site adapts to fit the substrate, like a glove that molds itself to fit the hand.
Keywords
lock-and-key, model, enzyme, action, induced fit, catalyst
