Ultraviolet radiation can induce both DNA crosslinking and double strand breaks.
Here is a paper reporting sequnce determinants of UV-induced intra-strand crosslinks:
Here is a paper where the authors propose that UV-induced double-strand breaks are a consequence of repair of oxidative lesions, rather than a ...
I'm here looking this up because scientist have discovered an extinct ant that was alive 95 million years ago that has naturally occurring metal mandibles. Mandibles on ants are essentially the same as fangs on spiders or teeth on humans. I was looking up to see if naturally occurring metal was or has been present on any other known creature. Apparently not. ...
I am reinforcing the statement made by the previous answer. Yes, histones are the most abundant proteins in the chromosome (Ohta et al. 2010); they can contribute up to ~38% of the chromosome mass. Other abundant chromosomal proteins include toposiomerase-IIα and condensin-I (SMC proteins). Apparently many non-chromosomal proteins i.e. proteins that ...
For grasses leaves tend to be inedible due do with the high quantity of silica deposited in the leaves to form structures known as phytoliths Wikipedia.
While this has been shown to inhibit digestion by insects (Hunt et. al., 2008, Massey et.al., 2006), I'm not aware of any studies on how this affects digestibility for humans. There are however anecdotes ...
Nutrient content of lettuce and grass can be similar.
According to USDA.gov, 100 g of green leaf lettuce contains:
Protein = 1,4 g
Digestible carbohydrates = 1.5 g
Calcium = 36 mg
Potassium = 194 mg
Magnesium = 13 mg
Fiber (cellulose or similar) = 1.3 g
According to Feedipedia (see Nutritional Tables), 100 g of Bahia grass contains:
Protein = 3.5 g
Actions: (1) Phosphoryliodide can combine with phosphatidylcholinesterase to form a complex of phosphatidylcholinesterase and phosphatidylcholine iodide. The latter can be further cleaved into phosphatidylcholine iodide to free the cholinesterase and restore its activity.
2) Phosphodium iodide can also bind with free organic phosphate esters in vivo, and ...
This is Encyclopedia about cerebroside
and this is about globoside
I hope this can help you.
Short Answer: As the comments mention, this is a hot topic for pseudoscientists to use as a selling point for their supplements. There is limited evidence that dietary acid intake significantly alters bone resorption, especially in the setting of normal renal function. This paper should answer all of your questions (emphasis mine):
Frassetto, Banerjee, ...
I'll try to explain this to you, but you should really look it up here: https://pubchem.ncbi.nlm.nih.gov/compound/beta-Levulose#section=3D-Conformer&fullscreen=true
This is the structure of beta-D-fructofuranose, as a 3D conformer. On paper, or as a 2D figure, we cannot visualize the -OH groups at positions 3 and 4.
They appear to be inside/outside ...
