Hello everyone. If you are using this video to study for a biolgy class, there are a few errors. Testosterone and estrogen, the sex hormones, are classified chemically as steroids (a type of lipid), not proteins as the video indicates. Also, it is true that triglycerides and steroids are both examples of lipids or fats, but the picture showing the glycerol plus three fatty acids is a triglyceride, a lipid family that includes the saturated and unsaturated fats. Cholesterol and Vitamins A and D are given as examples of triglycerides, but they are not. They belong to the steroid family of lipids. Steroids have a different structure than a triglyceride. Didn't want you to get these wrong if you have a test coming up. Good luck!
(incorrectly!) Lists estrogen and testosterone as examples of hormones made up of proteins...on the very next slide mentions that steroid hormones are lipids. Quality content there, buddy!
Really useful video, but estrogen and testosterone are not actually proteins as they are made from cholesterol, which is a lipid. Better examples of protein hormones might be growth hormone or thyroid stimulating hormone (TSH).
Suggestion: Can you speak a bit more clearly? So that the automatic captions can pick up everything... This could be helpful for deaf people... just an idea... you know
I think it says protein like testosterone and estrogen are not literally protein... Protein are used to produce energy and to synthesize molecules like hormones.. so it means that protein drives the reproductive hormones gets?😅
