1

Polypetide

10 or more AA joined together

2

Primary pttn structure

sequential order of the AA

3

secondary prtn structure

spiral shape form twist in AA chain
*alpha helix and beta pleated sheets

4

Tertiary ptn structure

unique 3D shape maintained by H bonds and disulfide bridges

5

Quaternary prtn structure

*Multiple tertiary prtn
polypeptides bond to form a larger prtn (globular or fibrous)

6

Denaturition

Prtns uncoil and lose their shape due to
Damaging substance
high fever (heat)
blood pH out of normal range ( acid & base)
during digestion

7

Zymogen

inactive form of enzyme
pepsinogen
trypsinogen

8

Pepsinogen

converted by HCl to pepsin
breaks down prtns into short poly and amino

9

trypsinogen

converted to trypsin
(chymotrypsin)
digest protns into single AA

10

proteases

pancreatic enzymes that complete prtn digestion

11

Gastrin

hormone that controls HCl prod and pepsin release

12

Active transport or specific carrier transoprt

absorbs AA through small intestine

13

fate of absorbed prtns

converted to glucose or fat
build new prtn
used for energy
released into blood to other cells

14

Albumin

Made in liver
transports proteins
regulates osmotic pressure of blood
controls fluid in body

15

Urea

prod. in liver
excreted by kidneys (Urine)

16

Ammonia

made in liver by nitrogen and hydrogen bonds
compound that upset acid basic balance
excreted- by making urea

17

Urea

Made-liver combines amonia with carbon diaxide
kidneys-excretes in form of urine
